I allow my students two attempts on a quiz with manually graded questions. Currently I give my students two attempts on a quiz with manually graded questions. I do this so that they can learn from their mistakes. However if I grade the second attempt first, then Canvas registers that assignment as graded and the two grades are averaged together. There is no way for me to know that there was a previous attempt that I need to grade unless I manually go back and look.
In this special circumstance, I need to know that I have ungraded attempts because if the ungraded attempt and the graded attempt are average togther, then the student will have an artifically low grade. It would also help the student to know that an attempt still needs to be graded.
